function Test-DbaFullRecoveryModel { <# .SYNOPSIS Find if database is really in the Full recovery model or not. .DESCRIPTION When you switch a database into FULL recovery model, it will behave like a SIMPLE recovery model until a full backup is taken in order to begin a log backup chain. This state is also known as 'pseudo-Simple'. Inspired by Paul Randal's post (http://www.sqlskills.com/blogs/paul/new-script-is-that-database-really-in-the-full-recovery-mode/) .PARAMETER SqlInstance The SQL Server instance to connect to. .PARAMETER SqlCredential Allows you to login to servers using SQL Logins instead of Windows Authentication (AKA Integrated or Trusted). To use: $scred = Get-Credential, then pass $scred object to the -SqlCredential parameter. Windows Authentication will be used if SqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials. To connect as a different Windows user, run PowerShell as that user. .PARAMETER Database Specifies the database(s) to process. Options for this list are auto-populated from the server. If unspecified, all databases will be processed. .PARAMETER ExcludeDatabase Specifies the database(s) to exclude from processing. Options for this list are auto-populated from the server. .PARAMETER Detailed Output all properties, will be deprecated in 1.0.0 release. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: DisasterRecovery, Backup Author: Claudio Silva (@ClaudioESSilva) Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .LINK https://dbatools.io/Test-DbaFullRecoveryModel .EXAMPLE Test-DbaFullRecoveryModel -SqlInstance sql2005 Shows all databases where the configured recovery model is FULL and indicates whether or not they are really in FULL recovery model. .EXAMPLE Test-DbaFullRecoveryModel -SqlInstance . | Where-Object {$_.ActualRecoveryModel -ne "FULL"} Only shows the databases that are in 'pseudo-simple' mode. .EXAMPLE Test-DbaFullRecoveryModel -SqlInstance sql2008 | Sort-Object Server, ActualRecoveryModel -Descending Shows all databases where the configured recovery model is FULL and indicates whether or not they are really in FULL recovery model.
